Tag: Binary Stars

Astronomers at The University of Leeds have found a pair of massive binary stars orbiting closer to each other than any system ever seen before. The star PDS 27, once thought to be a single star, was found to be just one member of a binary pair. The two stars orbit each other at a distance roughly equal to that between the Sun and Neptune. Roughly one-third of all stars in our galaxy are in systems containing two or more stars.
